碩士 / 國立中興大學 / 昆蟲學系所 / 105 / As an island, the topography in Taiwan is highly diversity in elevation. Taiwan located cover the climate zone of tropical and sub-tropical area. And the most worth to be mentioned is the high variation in topography. Therefore, the composition of fauna inventory and ecological survey of the distribution patterns will be the most interested one for biodiversity issue. The insect fauna inventory and monitoring in different elevation is obviously the significant topics. In this study, Orthopteran insects were investigated systematically by the elevational line along with the Central Cross-Island Highway in Taiwan. We set up 18 sampling plots and selected 12 distinct plant vegetation types according to elevation and environment. The specimens collected from February 2015 to July 2016 bimonthly by the sweep-net collecting method which is designed as quantitative sampling method for biodiversity monitory survey. Total of 2054 specimens collected by a standard procedure, and there are 7 families and 238 morpho-species identified recognized. There are 7 families of Orthoptera collected in this study, actually occupied 33.3% of Orthoptera families in the world based on Triplehorn et al. (2005). Besides of the serious damaged and unable to identify, there are 1067 individuals of Acrididae (55.3%) is the largest taxa and Gryllidae (17.9%) is the second large family in this study. The limitation of elevational distribution to the cricket (Gryllidae) was revealed as 1500m. To the morpho-species, Acrididae (29.8%) is the top one too. The second dominant family is Tetrigidae (29.0%). According to the morpho-species we redefined the elevational variation of orthopteran insect, mainly in low elevation ((500-700), 1000, 1100m); high (2000-2500m); then mid elevation (1500-2000m). Califera mostly in low elevation except small parts of Acrididae in high elevation. Ensifera partially in elevation and partially distributed various. Total influence to the habitat is very important and to the insect fauna of Orthoptera in each plot. The result show the similar trend in both insect fauna and habitat. At least the low elevation plot similarity. In addition, it was found that body size of Acrididae not smaller when elevation higher. This study is part of biodiversity survey by standard operation procedure. The elevation distribution pattern formed by comparing insect composition and fauna similarity is a simple and available way to define the biodiversity pattern in elevation distribution. The elevation distribution pattern of each higher taxon of Orthoptera insect will be applied in the environmental change as indicators and index of integrated biodiversity survey method.
